NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 7 50,7 55, datedJanuary 26, 1904.

Application filed June 15, 1903.

T0 at whom, it may concern:

Be it known that I, CHARLES M. DRENNAN, a citizen of the United States,residing in Boston, in the county of Suffolk and State of Massachusetts,have invented an Improvement in Non-Refillable Bottles, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention relates to a non-refillable bottle, and has for itsobject to provide a simple, inexpensive, and efficient bottle for thepurpose specified and one which can be made wholly of glass, therebyavoiding contamination of the liquid contents of the bottle.

The particular features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 represents in vertical section, with parts in elevation, asuflicient portion of a bottle embodying this invention to enable it tobe understood; Fig. 2, a cross-section on the line 2 2, Fig. 1; and Fig.3, a detail in plan, to be referred to.

The body portion a of the bottle may be of any desired shape and isprovided with a neck 6, which in accordance with this invention isprovided with an upwardly-inclined portion 4, intermediate cylindricalportions 5 6, for a purpose as will be described. The neck I) isprovided at its lower end with an annular inwardly-projecting andupturned flange 0, forming a seat for a valve (Z, which is provided witha stem 0, having laterally-extended guiding-wings f, which serve toguide the valve to its seat. The valve CZ, its stem 6, and wings f areand may be made in one piece of glass. Above the valve (Z and within thecylindrical portion 5 of the neck of the bottle is located a hollowfloat 70, preferably of glass, which is hermetically sealed and whichcooperates with the valve (Z to seat the same under certain conditions,as will be described.

The float i), is preferably substantially cylindrical in shape and ofsubstantially the inner diameter of the cylindrical portion 5 of thebottle-neck, which portion on its interior is provided withsubstantially vertical corrugations or flutes j, (see Fig. 2,) formingoutlet-channels k for the contents of the bottle.

Serial No. 161,453. (No model.)

Above the float h is located a disk on, preferably of glass and havingits edge or circumference inclined and ground to fit theupwardly-inclined portion 4 of the bottle-neck, which inclined portionof the neck is also ground, as indicated at n in Fig. 1, so that whenthe disk m is'placed in the neck of the bottle and practically seated itcannot be removed.

The disk m is provided with a plurality of holes or openings 0 throughit for the passage of the liquid'contents of the bottle, and the saidopenings are preferably conical in shape, with their apiees at the uppersurface of said disk. The disk m may be provided on its under side withnubs or projections 19, which serve as stops to limit the movement ofthe float toward the disk, and thus avoid said float closing the portsor openings 0 when the bottle is tipped in the act of pouring out itscontents.

I prefer to employ a second disk Q, which is also of glass and isprovided with a ground beveled or inclined circumference or edge whichcooperates with the ground inclined portion a of the bottle-neck. Thedisk q is preferably of larger diameter than the disk m and is providedwith conical holes or openings 7*, (see dotted lines, Fig. 1,) which arearranged out of line or staggered with relation to the openings 0 in thedisk m, so that if a wire is inserted through an opening 7 in the disk qit will strike the upper surface of the disk on and will not pass intoan opening in the lower disk m, thereby preventing the valve being heldup from its seat by a wire, and thus avoiding one of the methodsemployed for filling bottles of this class.

The upturned flange 0 forms an annular groove 8, which prevents a Wirefrom being inserted between the valve and its seat even if it werepossible to get the wire past the disk m. The bottle is normally closedby the cork or stopper 6.

In Fig. 1 the bottle is shown in its upright position and is supposed tobe filled With liquor up to the level represented by the dotted line 10.If now it is desired to pour out some of the contents, the bottle istipped or inverted and the valve (Z is moved bodily from its seatsufliciently to permit of the free escape of the liquor in the bottle,which passes through the channels is and through the holes in the disksm g.

After the bottle is emptied it cannot be filled by immersion or by meansof a vacuum or by pressure, as the float h under these conditionscarries the valve (Z to its seat. The valvestem 6 is made of such lengthas to prevent its withdrawal from the outlet-port of the bottle when thevalve is open to its fullest extent.

The construction of the parts herein shown and described is such as toenable them to be made solely of glass, which is very desirable, andwhile I prefer to use glass I do not desire to be understood as limitingmy invention in this respect.

I claim 1. In an article of the class described, in combination, a bodyportion having a neck provided with an upwardly inclined or beveledinner surface intermediate the ends of the said neck, aninwardly-extended flange form' ing a port or opening, a valvecooperating with said port and having a stem extended therein, a floatin the neck cooperating with said valve, a disk having a port or openingthrough it and provided with a beveled or inclined edge cooperating withthe beveled or inclined inner surface of the neck portion, and a seconddisk provided with a port or opening, and with a beveled or inclinededge cooperating with said inclined inner surface of said neck,substantially as described.

2. In an article of the class described, in combination, a body portionhaving a neck provided with an upwardly beveled or inclined innersurface, and an annular inwardly-projecting flange forming a port oropening, a

valve cooperating with said port and having a stem extended therein, afloat above said valve and cooperating therewith, and a disk providedwith an opening through it and with a beveled edge cooperating with thebeveled inner surface of the said neck, substantially as described.

3. In an article of the class described, in combination, a body portionhaving a neck provided with corrugations on its inner surface and with abeveled or inclined surface above said corrugations, aninwardly-projecting flange forming a port or opening, a disk valvecooperating with said port and having a stem provided withlaterally-extended wings movable in said port, a float cooperating withsaid valve, and a disk having a beveled edge which cooperates with thebeveled surface of the neck, substantially as described.

I. In combination, a glass bottle having a neck portion provided on itsinterior with an inclined ground surface, and with an annular flangeforming a port, a glass valve comprising a disk and a stem having Wings,said valve being located in the neck of the bottle and having its stemextended into the said port, a hollow glass float above the said valve,and a glass disk having a port or opening through it and provided withan inclined ground edge, which fits the ground surface of the neck,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence oftwo subscribing witnesses.

CHARLES M. DRENNAN.
